Abstract :

Nanoscale structures are quite important for manipulating and controlling light at the subswavelength scales at optical frequencies. Many nanophotonic structures such as photonic crystals, plasmonic crystals and metamaterials are being studied to fundamentally alter the emission behavior of light sources. This consists of substantially enhancing or totally suppressing it in some or all direction or guiding and bending it within few wavelengths. These capabilities are important for many advanced nanophotonics applications such as solid state lighting, low threshold lasing, non-classical light sources and optical communications. In this presentation we will discuss two and three dimensional photonic crystals composed of different key material systems utilized in modern nanophotonics including silicon, titanium dioxide, and III-nitrides and how they can be utilized to create nanophotonic devices. In addition we will also discuss where appropriate plasmonic and metamaterials for such purposes.
